Lessons

Monday-Tuesday, 01/12-13: Waves on a String (or Slinky) Wave motion allows us to send energy from one place to another. Before we learn how that energy can carry information, let's learn more about the properties of wave motion!
Friday, 01/16: EQ1: Wave Motion. This quiz offers 5 questions randomly selected from a larger bank of questions. Try it over and over to see if you have a complete picture of wave motion! (As usual, your best score will be recorded. Feedback on wrong answers will be enabled on Monday.)
Tuesday, 01/20-21: Sound Amplitude & Frequency. This lesson reviews the Concepts TI1 below, and gives an opportunity to demonstrate mastery of these concepts through Mac's Garage Band Program! Click here for Garage Band Help.
Thursday, 01/22: Hearing. We will finish notes under TI1 below, and follow up with Quia quiz EQ2 .
Monday, 01/26: Cell Phone Debate Click here to review the debates we conducted relating to cell phone safety.
Friday. 01/30 & Monday, 02/02: Wave Speed Equation Click here to learn the concepts and the math behind wave motion.
Thursday, 02/05: Electromagnetic Spectrum Click here to explore two common applications of the EM Spectrum.
Monday, 02/09: Modulation: How does a sound wave mix with a radio wave to carry songs over a broadcast?
Tuesday, 02/10:Review Game

Concepts

TI1: Information can be carried through waves. (amplitude & frequency)
TI2: Electrical signals can be converted into sound and vice versa. (speakers, microphones)
TI3: A moving charge creates EM radiation. (EM spectrum)
TI4: All radiation moves at the same speed. (wave equation)
TI5: Tuners can isolate information at a specific frequency. (resonance)
TI6: Sound waves differ from radio waves in important ways. (Lucille Ball's fillings)
